I'm trying to get a 160Mhz AC connection between a Netgear XR500 (based on Ansuels repo) and a AX200 Intel Wifi card running under Linux (Fedora & iwlwifi driver).
But according to the OpenWrt stats the connection is still 80Mhz "only" (rx, tx stucks at 40Mhz channel width)
Station 9c:fc:e8:dd:5b:49 (on wlan0) inactive time: 70 ms rx bytes: 371572 rx packets: 2414 tx bytes: 3052622 tx packets: 3222 tx retries: 0 tx failed: 0 rx drop misc: 0 signal: -53 [-59, -56, -56, -58] dBm signal avg: -52 [-59, -55, -56, -58] dBm tx bitrate: 360.0 MBit/s VHT-MCS 9 40MHz VHT-NSS 2 tx duration: 4551547 us rx bitrate: 780.0 MBit/s VHT-MCS 8 80MHz short GI VHT-NSS 2 rx duration: 154876 us airtime weight: 256 authorized: yes authenticated: yes associated: yes preamble: long WMM/WME: yes MFP: yes TDLS peer: no DTIM period: 2 beacon interval:100 short slot time:yes connected time: 100 seconds associated at [boottime]: 667419.197s associated at: 18446725627465128437 ms current time: 18446744073541782965 ms
According to the client, the connection is 160Mhz (at least for rx):
iw dev wlp3s0 link
SSID: XR500 freq: 5180 RX: 2933424 bytes (3200 packets) TX: 318959 bytes (2091 packets) signal: -42 dBm rx bitrate: 1560.0 MBit/s VHT-MCS 9 160MHz VHT-NSS 2 tx bitrate: 780.0 MBit/s VHT-MCS 8 80MHz short GI VHT-NSS 2 bss flags: short-slot-time dtim period: 2 beacon int: 100
The iperf3 speed whatsoever is the same as a regular 80Mhz connection
My questions is: is the Intel AX200 capable of 160Mhz width channels with the linux iwlwifi driver?
BTW: the 160Mhz mode works with Windows 10 and the AX200 and the same XR500 router.
